ELVIN XV. DAVIS, OF GENEVA, MINNESOTA.

CAR-COUPLING.

$PECIFICATIQN forming part of Letters Patent No. 320,337, dated June 16,1885.

Application filed April 11, 1885. (No model.)

To all whom it may concern:

Be it known that LELWIN \V. DAVIS, a citizen of the United States, and aresident of Geneva, in the county of Freeborn and State of Minnesota,have invented certain new and useful Improvements in Car-Oouplings; andI do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, which form a part of this specification,and in which- Figure l is a perspective view of my inipror edcar-coupling. Fig. 2 is a longitudinal vertical section of the same; andFig. 3 is a horizontal section on line w m, Fig. 2.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of car-couplings in which acommon link is engaged within thedraw-head bya spring-actuated hook; andit consists in the improved construction and combination of parts of thesame, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the draw-head,which is formed with the usual recess, B, for the reception of the link,and the bottom of this recess has a longitudinal slot, 0, extending fromnear the i l I l I l l l l forward end of the same, while the top of theI recess has a short slot, D, through which passes a bar, E, projectingupward from a bar, F, pivoted at its inner end in the inner end of thelongitudinal slot 0, and having its outer end formed into anupward]y-proiecting hook, G. The under side of the hooked bar isprovided with a downwardly-projecting lug, H, to which one end of aspiral spring, I, is secured, while the lower end of the said spring issecured to an upwardly-projecting lug, J, upon a downwardly-projectingoblique bar. If, secured at its upper end to the bottom of j thedraw-head, and extending withjits free end under the pivoted hooked bar,the spring serving to force the hooked bar up into the longitudinal slotin the bottom of the draw-head. The recess in the draw-head has atransverse piece, L, against which the link may abut when inserted intothe recess, and two curved side pieces, M M, are secured at their innerends to this cross-piece, and at their outer ends to the sides of themouth of the recess of the draw-head, forming curved guides for thelink. A flat spring, 0, is secured at its inner end to the upper side ofthe cross-piece, and has its outer end curved upward, so as to bearagainst the roof of the recess, and this outer end of the spring isslotted or bifurcated, so as to fit over the upper end of the hook uponthe forward end of the pivoted bar.

P is the link, which is of the usual construction, and it will be seenthat when the link is introduced into the mouth of the recess in thedraw-head the curved side guides will guide the link straight, while thecurved springguide will guide the link and force it over the hook,whereupon its bifurcated end will engage the end of the hook and preventthe link from slipping over the end of said hook.

For the purpose of depressing the hooked bar, when it is desired touncouple the link, the upwardly-projecting bar E has a transversevertical slot, Q, into which one arm of an elbow-lever, R, projects,which lever is pivoted upon the top of the draw-head, and by forcing theupwardly-projecting arm S of this elbow-lever toward the upright bar thesaid bar and the hooked bar may be depressed, which will allow the linkto be withdrawn from the draw-head.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. In a car-coupling, thecombination of a hooked pivoted bar having a spring for forcing itupward and pivoted in the bottom of the recess in the draw-head, a flatspring socured at its inner end in the inner end of the recess of thedraw-head, and having its outer end curved upward and bifurcated to fitwith its bulged forward end over the hook of the bar, the link, andmeans for depressing the hooked bar, as and for the purpose shown andset forth.

2. In a draw-head havinga spring-cushioned hook in its bottom, twocurved side guides, M M, in combination with the flat spring 0, havingits outer end bifurcated and fitting over the end of the hook, as andfor the purpose shown and set forth.

2 L amiss-1 3. In a car-coupling, the combination of the draw-headhaving the recess B, slot 0 in its bottom, and slot D in its top, bar F,pivoted in slot 0, and having spring I, forcing it upward, and formedwith hook G at its outer end, cross-piece L, curved side guides, M M,flat spring O,having its outer end bifurcated, the link, and. theuprightbar E and elbow-lever R, for depressing the hooked bar, as and for thepurpose shown and set forth. a

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
